Abstract

Dryer bars having certain defined void volumes.

Claims

exact text as granted — not AI-modified
1. A dryer bar comprising a dryer bar composition, wherein the dryer bar composition comprises a void volume percentage from 0.33% to about 20% with respect to the total volume of the dryer bar composition, wherein said dryer bar composition comprises from about 41 wt % to about 61 wt % of fabric softening active and about 38 wt % to about 55 wt % of a carrier, wherein the softening active is a quaternary ammonium compound suitable for softening laundry. 
     
     
       2. The dryer bar of  claim 1 , wherein the dryer bar composition comprises a void volume from about 1% to about 15%. 
     
     
       3. The dryer bar of  claim 2 , wherein the dryer bar composition comprises a void volume from about 3% to about 10%. 
     
     
       4. The dryer bar of  claim 3 , wherein the dryer bar composition comprise a void volume from about 3.19% to about 7.45%. 
     
     
       5. The dryer bar of  claim 2 , further comprising a plastic carrier functionally attached to the dryer bar composition. 
     
     
       6. The dryer bar of  claim 1 , wherein the dryer bar composition is essentially free of any detersive anionic surfactants. 
     
     
       7. The dryer bar according to  claim 1 , wherein the dryer bar composition comprises a void volume from about 3% to about 10% with respect to the total volume of the dryer bar composition and wherein the dryer bar composition is made by a single screw extrusion process. 
     
     
       8. The dryer bar of  claim 1 , wherein said carrier is wax. 
     
     
       9. A method of softening fabric comprising the step of installing a dryer bar inside an automatic laundry drying machine, wherein the dryer bar comprises a fabric softening composition, wherein the composition comprises a quaternary ammonium compound and wherein the composition comprises a void volume from about 3% to about 10% with respect to the total volume of the composition. 
     
     
       10. The method according to  claim 9 , wherein said composition comprises from about 41 wt % to about 61 wt % of fabric softening active and about 38 wt % to about 55 wt % of a carrier. 
     
     
       11. The method according to  claim 10 , wherein said carrier is wax. 
     
     
       12. The method according to  claim 9 , wherein said dryer bar further comprises a plastic carrier functionally attached to the composition. 
     
     
       13. The method according to  claim 9 , wherein said composition is essentially free of any detersive anionic surfactants. 
     
     
       14. The method according to  claim 9 , wherein said composition comprises from about 41 wt % to about 61 wt % of fabric softening active. 
     
     
       15. The method according to  claim 14 , wherein said carrier is wax. 
     
     
       16. The method according to  claim 9 , wherein said composition comprises from about 38 wt % to about 55 wt % of a carrier. 
     
     
       17. The method according to  claim 16 , wherein said carrier is wax. 
     
     
       18. The method according to  claim 9 , wherein said composition comprises a void volume from about 3.19% to about 7.45%. 
     
     
       19. The method according to  claim 18 , wherein said carrier is wax. 
     
     
       20. The method according to  claim 18 , wherein said composition comprises from about 41 wt % to about 61 wt % of fabric softening active.
